Abstract

The present disclosure provides a light string with multiple parallel wires and a method of manufacturing the light string with multiple parallel wire. The light string includes a positive wire disposed axially and a negative wire disposed in parallel with the positive wire. Positive solder joints and first disconnection points are disposed on the positive wire. Negative solder joints and second disconnection points are disposed on the negative wire. A welding lamp area is formed by a positive solder joint and a negative solder joint. An LED lamp bead is attached to a front or a side of the welding lamp area. The first disconnection points and the second disconnection points are staggered, such that LED lamp beads disposed between the positive wire and the negative wire are serial-parallel connected.
